MULTI-FINGER CALIPER ANALYSIS AND REPORTING · 2019. 12. 3. · caliper and pipe thickness log data. Used globally by leading operating and service companies, MIPSPro maximizes data

evcam.com

MIPSPro is sophisticated analysis and visualisation software that enhances the interpretation of caliper and pipe thickness log data. Used globally by leading operating and service companies, MIPSPro maximizes data value by efficiently identifying and diagnosing well integrity issues.

MIPSPro runs independently of the instrument used to acquire the log data, reading field data in LAS, DLIS and other industry standard formats.

Key Features and Benefits Interactive processing algorithms prepare caliper and thickness data for analysis. Workflows calculate multiple penetration and restriction statistics - readily identifying typical corrosion, scale build-up, drilling wear and other deformation anomalies. MIPSPro uses synchronised 2D and 3D views to visualise and communicate results.

Multiple output options allow results to be presented to end-users in their chosen format. An integral reporting module delivers customised Word, Excel and PDF documents. Scaled log plots can be produced in TIFF or PDF format and processed curve data can be output in LAS format. MIPS3D can produce 3D movie clips and 2D and 3D scenes can be saved and communicated to the end user with the license free MIPSView package, exactly as the analyst viewed them.

MIPSPro gives the analyst a comprehensive set of processing options to prepare the data for interpretation. These include:

• Centralising field data – almost always required for accurate analysis of pit depths

• Depth Correction• Merging and Splicing

of multiple runs• Orientation to top of hole• Editing of poor data• Recalibration to known IDs

MIPSPro assists in efficient interpretation of log data through:

• Automation of time consuming processes

• Quick access to commonly used commands

• Pre-population of default options for workflows

• Semi-automated collar identification allowing joints to be quickly identified and interactively edited prior to further analysis

An extensive statistical analysis of penetration and restriction data provides the basis for quantitative interpretation.

With more than 30 statistical results available for each joint, the analyst has full flexibility in the reporting of pipe integrity.

Tubular details are entered in a well schematic style interface, producing a graphical well sketch and auto-populated tubular dimensions.

The joint detection processor provides automated picking and QC of tubing and casing collars. Joint-by-joint statistical analysis can then be performed. MIPSPro allows many parameters and user preferences to be saved and reused in future projects.

Uncentralised field data, on the left, produces inaccurate corrosion and scale analysis. Centralised caliper data shown on the right after processing is now optimised for further interpretation.

The integrated reporting module in MIPSPro allows the analyst to produce structured, custom built reports in Word, PDF or TIFF format. Features of the statistical reporting include histograms, bar charts, joint analysis tables and pipe grading. Log sections, 2D cross sections and 3D views are all easily captured and added to the written report. Pre-prepared introductory and concluding text sections complete the written report. MIPSPro reports are supported with API style log plots, LAS output and presentation of data in MIPSView.

MIPSView is provided as a license free version of the 2D and 3D viewers for distribution to the client, allowing interaction with images exactly as the analyst viewed them. Visualising data in this way aids communication and understanding of the results. The analyst can define scenes in MIPSPro and the client can open these again in MIPSView.

Processing History within MIPS captures details of all parameters and processes allowing QC, audit or reconstruction of the analysis.

History details can be embedded in LAS files or displayed in the MIPS Viewer.

Right: MIPS captures the processing history in the header of the data files. This can be displayed alongside the viewers and output to the header of a LAS data file.

Example Joint statistics table from MIPSReport.

MIPSView shares the same viewer as MIPSPro, allowing the analyst to communicate important data features to the client.

Global analysis allows the user to find the largest wall penetrations, cluster neighbouring penetrations, and show the relative size of the clusters in a summary graph. Overlays can be used to compare passes and for time lapse analysis.

MIPSView has the same 3D viewer as MIPSPro. The analyst can define a 3D display which will be directly opened by the client.
